Proteus vulgaris is a rod-shaped, nitrate-reducing, indole-positive and catalase-positive, hydrogen sulfide-producing, Gram-negative bacterium that inhabits the intestinal tracts of humans and animals. It can be found in soil, water, and fecal matter.

2023年1月25日 · Proteus vulgaris is a Gram-negative, motile, and rod-shaped bacterium that belongs to the Enterobacteriaceae family. It is an opportunistic human pathogen that can be found in soil, water, and fecal matter. P. vulgaris is known for causing wound and urinary tract infections. 1-2 days on inanimate surfaces.

2022年11月18日 · It is a gut bacterium inside our intestines whereas, outside the gut, it can cause serious infections. It is an etiological agent of catheter-associated UTI (CAUTI), sepsis, and septic shock if the infection goes up and causes cystitis and pyelonephritis.

Proteus are Gram-negative rod-shaped bacteria of the family Enterobacteriaceae. They are widely distributed in nature and also occur as normal intestinal flora of humans. An opportunistic pathogen, they are one of the common causes of urinary tract infections (UTIs) and are associated with infection-induced renal stones.

The genus Proteus currently consists of five named species (P. mirabilis, P. penneri, P. vulgaris, P. myxofaciens, and P. hauseri) and three unnamed genomospecies (Proteus genomospecies 4, 5, and 6).

Proteus spp. are motile, gram-negative bacilli that do not ferment lactose and are distinguished from other Enterobacteriaceae by their ability to deaminate phenylalanine and lysine.

Proteus spp. bacteria were first described in 1885 by Gustav Hauser, who had revealed their feature of intensive swarming growth. Currently, the genus is divided into Proteus mirabilis, Proteus vulgaris, Proteus penneri, Proteus hauseri, and three ...

2024年1月25日 · Proteus vulgaris is considered an opportunistic pathogen that can cause infections in humans, particularly in those who are immunocompromised or have underlying medical conditions. P. vulgaris is found worldwide and is commonly found in soil, water, and the intestinal tract of humans and animals.

It covers the pathogenic bacterium Proteus vulgaris and a method for rapid identification of bacteria from clinical specimens. The genus Proteus is classified in the enteric bacteria, together with Escherichia coli, Salmonella, Shigella, Enterobacter and Serratia.

2020年12月1日 · Proteus vulgaris is one of five bacterial species within the genus Proteus, and one of three species within the genus that are opportunistic pathogens (1). P. vulgaris is a rod-shaped, Gram negative bacterium between 1-3 microns in size, and is extremely motile, utilizing peritrichous flagella as its source of motility (2).
